' This present invention relates to improve ,ments in a mowing machine, appertaining particularly to a device of this character adapted for attachment" to a railway car .5 truck, the cutting mechanismflof which is.

intended, as the car advances along the track to operate 'onthe grass growing at the side thereof. ,g l

An object is to cutting mechanism isactuated by the rotation of one of the'truck'axles, through the medium of gears and xaupitman. 4

Another object is to provide a mowing machine whose cutter barmay be initially positioned at approximately the necessary height and thereafter, while running, ad justed within limits to the desired elevation to .compensate for undulations. in the land 9 along the trackor the like while' the vertical. hanging of the cutter bar intoloperativeand.

almost upright, position is readily effected on the operation of. additional means provided for thatpurpose.

Astill further object is theprov-isioniofa device of the character described charactere ized by structuralsimplicity, ease. and econ; omy of operation and capableiof production rendered,-

at ar'easonable cost, being thereby To. the accomplishment lated objec'ts my invention resides in the construction, combination'and arrangement of ,7

parts as shall be hereinafter more fully de-' scribed illustrated in they accompanying drawings andfointed outin the claims h'ere* unto appende The invention will be bestunderstood and can be most clearlydescribed when reference is had to the drawings, forming a part ofthis disclosure, wherein like characters indicate.

The manually operated clutch,15 slides longitudinallyof theshaft on akey way and is adapted fo rgengagement with the bevel gear 16 whichnon mally runs free. U i

' A transmission shaft 17 carried by bearings: in the hou'sing'14 has a bevel gear 18' onone end that; meshes with the clutchengaging bevel gear l6 a'nd is provided on the remote end with a crankmember119 that actuates the 10- I Cutting knife through the medium of a pitman 20.

Configurated on the outer side of the housing 14 near the end receiving the shaft 10, are a pair of lugs 21 through which horizontally aligned perforations 22 are bored to accommodate a bearing pin 23. n

The cutter bar 24: of usual design is slung 7 under the head 25 at its inner end to which it ishingedly connected. This head is rigid with the main supporting arm 26 that is pivoted horizontally at its opposite end on the .shaft 17 between the crank 19 and the ad cradle'beam 8 and acts as fulcrum for a lever 29 that is pivoted to its offset upper end 80.

The outer end of the lever 29,carries a chain 31 by which it is connected to the head while from theiinner end of the lever 29 a line 32 extends that passes downwardly under a pulley 33 onthe beam .8 at the adjacent side of the car, across thevehicle and over a corresponding pulley on the opposite side of the car and terminallyconnects with the lower end of a manually operated lever Bethe upper or. handle end of which is offset on the pivot rod 35 and is provided-with dog mechanism to engage the arcuate. rack 36. The vertical hinging of the cutter bar-carrying arm 26 by the manipulation of'the lever 34 will thus be clearlyseen. v r

'Pivoted atits' apex to the. cutter bar head 25 and'atits lower'end to the cutter bar frame 24 is a bell crank 37 whose upper end extends substantially above thehead-25. A cable38 anchored thereto passes downwardly under a pulley mounted on the supporting arm 26 and thence to a lever 89 fastening thereto at a point between the fulcrum and the handle end. {As in the previous case, thislever is also manually adjusted and is heldin any de sired position by the action of a spring dog of usual form engaging an arcuate rack 40. Both the lever 34 and the rack 40 are mounted on the cradle beam 8 remote from the driving axle 6 as are the lever 34 and its co-operating rack 36. V

The'construction and relation of the several parts having beenthus described there now follows a brief reference to the use and mo-dus operandi of the invention.

As the car is advanced along the track by any approved draft means,*the clutch 15 is thrown into operative position producing A post or standard 28 is mounted on :the outer end of the adjacent the reciprocation of the knife in the cutter bar through the medium of the pitman 20. If the ground along the track is low the cutter bar is lowered by adjustment of the lever 3% that drops the head 25 while if the bank receeds quickly or enclines sharply upwardly the cutter bar is brought to the proper angular position by manipulation of the lever 39 that hinges the bell crank 87. Thus any and all the variations in the lie of the land alongside the track can be readily cared for by the versatile operations of this improved mowing machine.

Fromthe foregoing description taken in connection with the accompanying drawings, it will be manifest that :a mowing machine is provided that will fulfill all the necessary requirements of such a device, but as many changes could be made inthe above description and manyapparently widely diflerent embodiments of my invention constructed withinthe scopecof the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawings shall. be interpreted as illustrative and not ina limited sense.

That I claim'as new and desire to secure by Letters Patent is Q 1. A railway mowing machine including the combination of a wheeled truck; a cradle projecting laterally from one side of said truck; a transverse rotatable shaft driven by one of the axles of the wheeled truck; a casing supported at the outer end of said cradle; a supporting arm hingedly mounted on'said casing; a cutter bar headcarried by said supporting arm; a cutter bar pivoted for vertically swinging adjustment in said cutt'er bar head; transmission mechanism within said casing and driven by said transverse shaft; and driving mechanism connecting said transmission mechanism with said outter bar'to operate the latter.

2. A railway mowing machine including the combination of a wheeled truck; a cradle projecting laterally from one side thereof; a cutterbar head hingedly mounted at the outer end of said cradle; means for regulating the position of said cutter bar head with respect to said cradle and the wheeled truck; a cutter bar operable in said cutter bar head; means supported by said cradle for operating said cutter bar from one of the axles of said wheeled truck; a casing carried by said cradle for part of the last mentioned means; and means for tilting said cutterbar to different inclined planes independently of the adjustment of said cutter bar head.

In testimony whereof I hereunto affix my signature.
